During a post-resuscitation debriefing, what observation suggests a need for improvement?

A chest compression fraction refers to the percentage of time during a cardiac arrest when chest compressions are being performed, compared to the total resuscitation time. The higher the chest compression fraction, the more effective the resuscitation efforts are likely to be, as it indicates that compressions are being prioritized and interruptions are minimized.

In this context, a chest compression fraction of 58% suggests a significant need for improvement. This indicates that less than 60% of the time during the resuscitation effort was spent providing compressions, which is well below the recommended target of 80% or more. Low chest compression fractions can lead to inadequate blood flow and reduced chances of a successful return of spontaneous circulation. Therefore, this metric serves as a clear indicator that the team may be experiencing delays in delivering compressions, possibly due to interruptions for ventilation or other factors during the resuscitation process.

Conversely, the other options reflect higher percentages, indicating better performance during the resuscitation efforts. A chest compression fraction of 70%, 82%, and 90% shows that the team maintained a continuous and effective approach to compressions, which would be viewed as more successful in promoting positive outcomes for the patient.
